Cleaning and Maintenance Instructions
IMPORTANT: Strong alkaline or acid-based chemicals and cleansers should not be used to clean
the MG-2/TT Express®. If these chemicals come in contact with the Terreon® surface,
wipe off the surface immediately and flush with soapy water. Avoid unnecessary or
prolonged contact with hot pans and objects.
Terreon® and panel maintenance
The bowl, sprayhead and pedestal end caps are made of Terreon®, a solid cast polyester resin
material. Terreon® resists chemicals, stains, burns and impact, and is repairable with everyday cleaners or
fine-grit abrasives. The panel is made of stainless steel. With regular cleaning, your MG-2/TT Express® will
provide years of dependable service.
Stainless Steel Access Panel cleaning
Stainless steel is extremely durable, and maintenance is simple and inexpensive. Proper care, particularly
under corrosive conditions, is essential. Ordinary deposits of dirt and grease are quickly removed with soap
and water. Whenever possible, the metal should be thoroughly rinsed and dried after washing. To remove
tightly adhering deposits, use stainless steel polishing powder. In all cases, rub in the direction of the stainless
steel grain.
IMPORTANT: Never use ordinary steel wool or steel brushes on stainless steel. Always use
stainless steel wool or stainless steel brushes.
Avoid prolonged contact with chlorides, bromides, thiocyanates, and iodides on stainless steel equipment,
especially if acid conditions exist. Do not permit salty solutions to evaporate and dry on stainless steel. The
appearance of rust streaks on stainless steel leads to the belief that the stainless steel is rusting. Look for the
source of the rust in some iron or steel particles which may be touching, but not actually a part of the stainless
steel structure. NOTE: Strongly acidic or caustic cleaners may attack the steel causing a reddish film to
appear. The use of these cleaners should be avoided.
Terreon® Bowl, Sprayhead and Pedestal End Cap cleaning
IMPORTANT: To sustain original finish, additional care is recommended for dark colored solid
surfaces to maintain highest quality color. The original luster can be maintained by
periodically applying furniture polish, mineral oil or a solid surface cleaner or polish.
For more information on restoring dark colors, see Bradley document #1505. Length
of time between applications varies with usage.
• For regular cleaning, use standard commercial or household products such as Formula 409® or Windex®.
• Remove tough stains with Ajax®, Comet® or Soft-Scrub® and a green Scotch-Brite® pad or lightly sand in a
circular motion with 240 grit wet/dry sandpaper. The finish can be renewed with a maroon Scotch-Brite® pad.
• Remove scratches with a green Scotch-Brite® pad. The finish can be renewed with a maroon ScotchBrite® pad. Remove hard water build-up with a mild solution of vinegar and water.
* Use of brand names is intended to indicate a type of cleaner and does not constitute an endorsement.
** It is emphasized that all products should be used in strict accordance with package instructions.
• Repair kit: A repair kit is available from Bradley to repair/patch the Terreon® bowl and shelf. Contact your
Bradley representative to order a repair kit and be sure to specify color.

Troubleshooting Solenoid Valve (VAC)
CAUTION: Turn off electrical and water supplies to unit before troubleshooting.
Problem: An individual operating station fails to shut off and drips.
Cause: There is debris trapped between the diaphragm and the valve seat.
Solution: Remove debris between diaphragm and the valve seat.
1. Remove the three #8 Phillips-head screws that hold the solenoid valve assembly together. Be careful not
to lose the armature or spring (see Figure 13 on page 19).
2. Remove the diaphragm. Remove any particles that have been trapped between the diaphragm and the
valve seat. Rinse off the diaphragm and inspect for damage. Make sure the center orifice and both small
side orifices are open.
3. Reassemble in reverse order, being careful not to overtighten the Phillips-head screws or you may crack
the plastic valve body. Tighten until the armature plate makes contact with the plastic body.
4. Reconnect the wiring per diagram on page 12.
Problem: An individual operating station fails to turn on.
Cause: A failed coil for the valve or loose electrical connection to the terminal.
Solution: Test the station to determine cause.
1. Disconnect the wires from the coil of an adjacent valve. Disconnect the wires from the problem valve and
reconnect to the adjacent valve.
2. Turn on electrical and water supplies to the unit. Pass your hand in front of the sensor of the problem
station, and the adjacent station should turn on.
If the adjacent station turns on and cycles normally, replace the coil on the problem valve.
If the adjacent valve fails to turn on, inspect the wires from the sensor cable and do the following:
• make sure there are no breaks and that the fully insulated disconnect terminals are firmly crimped in
place;
• turn off the electrical and water supplies;
• reconnect to the adjacent valve and turn on the electrical and water supplies to the unit;
• pass your hand in front of the sensor. If the station still fails to turn on, replace the sensor
(see page 19).

Thermostatic Mixing Valve Troubleshooting
Before attempting to troubleshoot the valve or disassemble the components, check for the following conditions:
• If stop valves are used, make sure that they are fully open.
• Make sure that the hot and cold inlet pipes are connected properly, and that there are no cross-connections or
leaking stop valves.
• Check the hot water heater output to make sure that it is at least 10° F above the set temperature.
Be sure to close the appropriate shut-off valves prior to disassembly of the valve and reopen the valves after inspection and
repair is complete.
Problem
Cause
Solution
External leaks.
Damaged cartridge or O-rings.
Replace cartridge with part number 269-1927
Improper water
temperature or
temperature
fluctuation.
Hot water supply is not 10° above desired set point.
Increase hot water supply temperature
Valve temperature is not properly set.
Adjust the temperature as shown on page 13, step 8.
Limited water
flow.
Dirt and debris have built up in the valve or strainer.
1.Check to make sure both hot and cold supplies are
connected to the Navigator mixing valve and that they
have water flow.
2.Remove cover and U-clip. Remove the cartridge and
clean the strainer. It is not required to grease cartridge,
however if desired, use silicone grease only. Do not use
grease on check valves.
